    Matrix operations

    The matrix matrix window contains three matrix containers (value arrays): A, B and X. Mathgrapher handles real matrices only. The results (eigenvalues, eigenvectors) may be complex. The screen view show the operations that can be performed on these matrices:
    Matrix addition X = A + B
    Matrix multiplication X = A B
    Transpose of a matrix X = Transp (A)
    Solve AX=B (Least squares) solution of linear system of equations. Find solution for A X = B
    Eigenvalues and Eigenvectors of A. Eigenvalues/vectors
    Inverse of A X = Inv (A)  so that X A = 1
    Determinant of A Det (A)

    Matrices: Eigenvalues/vectors

    Eigenvalues and Eigenvectors of a (real) Matrix

    Definitions: => eigenvalues , eigenvectors
    The (complex) eigenvalues and eigenvectors of a real matrix are calculated and the results are written in the file Results.out and shown in the Results window.
